What to do to avoid colds and flu?

Cold weather can weaken your immune system, making it easier for cold and flu viruses to spread. There are steps you can take to reduce your risk and prevent these seasonal infections.

When the weather turns to winter, the amount of sunlight reaching the ground will be weaker. Skin that is not exposed to enough sunlight will not produce enough vitamin D. Lack of vitamin D will make the immune system unable to function effectively, according to the health website Healthline (USA).

Sneezing is a common symptom of both the flu and the cold.

In addition, cold and dry weather in winter can reduce the mucous membranes in the skin, nose, eyes and lungs. As a result, bacteria and viruses that cause disease can easily enter the body. To prevent colds and flu when the weather turns cold, people can apply the following methods:

Wash your hands often

Washing your hands frequently with soap and water will help eliminate cold and flu viruses. This simple habit will help prevent the spread of viruses, especially after contact with surfaces such as doorknobs, tables, chairs or objects in hospitals and office buildings.

Eat nutritious food

Eating a well-balanced diet provides important nutrients for the immune system. Plants such as citrus fruits, guava, green leafy vegetables and nuts provide rich sources of vitamins C, D, E and zinc. All of these have immune-boosting effects.

Drink plenty of water

Cold winter temperatures are often accompanied by dry air. This can cause the skin, nasal mucosa, and eyes to dry out. Therefore, drinking enough water will help maintain moisture in these areas. In particular, maintaining moisture in the nose and lungs can help reduce the risk of respiratory infections.

Use a humidifier

Using a humidifier is an effective way to help maintain humidity in your home. A good level of humidity will help reduce respiratory irritation, making it easier for people with colds and flu to breathe and reducing sore throats.

Get enough sleep

Everyone should ensure they get 7 to 8 hours of sleep each night. Lack of sleep not only reduces concentration and causes fatigue, but also weakens immune function.

Stay active

Regular exercise improves circulation and immune function, which can reduce the risk of catching colds and flu. If the weather is too cold, people should prioritize indoor exercises such as yoga, stretching or working out at the gym, according to Healthline.
